Though unsupported, kernel 4.17.1 worked for me for wi fi. 4.15.x didn't work for me.

Code: Select all

 uname -r

will give the kernel you have booted to.

[mrmajik45]

4.15.0-24-generic

So how do I install 4.17

So how do I install 4.17

I wouldn't as I bet you would be in worse shape with wifi. In terminal do

Code: Select all

sudo apt update && sudo apt-get install bcmwl-kernel-source

Reboot

[mrmajik45]

Nope still at 4.15

See the wireless script link in my signature and post results, also post results for

Code: Select all

mokutil --sb-state

While this installs, my system is also stuck in software rendering mode.
EDIT:

SecureBoot enabled

[JeremyB]

Reboot and disable Secure Boot in Bios/UEFI. You might want to start a thread about the software rendering mode

[mrmajik45]

I did, no replys

Is this a working Wi-fi connection? Yes it is.
Here's a link to the software rendering problem viewtopic.php?f=59&t=272570

My laptop has the Broadcom wireless that your laptop has. To fix the no wi-fi issue, I did the following: 1) connected laptop to ethernet, 2) ran Driver Manager, 3) applied the bcm driver offered, 4) disconnected from ethernet, 5) re-started networking and voila wi-fi worked.

I hope this can sort your wi-fi issue.
